Parts Bags

The installation hardware for the transducer is included in labeled bags. As you complete the installation process, each procedure begins with a reference to the label on the parts bag needed to complete the procedure. You can use this table to review or verify the parts bags needed for the installation procedures.

NOTE: You should leave all parts in the labeled bags until you are instructed to open a bag in the instructions. Not all hardware is used for all installation types.

Mounting Considerations

Using the hardware supplied, you can mount the transducer on your trolling motor in one of three ways:

Perspective Mount

(Installing the Transducer on the Perspective Mode Mount, page 4)

• You can mount the transducer on the trolling motor shaft using the perspective view mount and bracket.
• When using the perspective view bracket, the transducer can be used for perspective, downward, and forward views.

Barrel Mount

(Installing the Transducer on a Trolling Motor Barrel, page 8)

• You can mount the transducer on either side of the trolling motor barrel.
• When mounted on the barrel, the transducer can be used for downward and forward views.

Shaft Mount

(Installing the Transducer on the Trolling Motor Shaft, page 10)

• You can mount the transducer on either side of the trolling motor shaft.
• When mounted on the shaft, the transducer can be used for downward and forward views.
• You cannot use perspective view when mounting the transducer directly to the trolling motor shaft, but it allows for a lower-profile installation.

When planning the installation, you should observe these considerations:

• You must angle the transducer correctly for the selected view to work properly.
• Installing the transducer with the included knobs allows for tool-free transitions between sonar views.
• You can use the included low-profile hardware instead of the knobs for a more permanent transducer view position.
• You should mount the transducer in a location where it will not be jarred when launching, hauling, or storing.
• You must install the sonar module in a location with adequate ventilation where it will not be exposed to extreme temperatures.
• You should mount the sonar module in a location where the LEDs are visible, where the cables can be connected, and where the device will not be submerged.

Cable Considerations

NOTICE

Zip ties and cable clamps can over-tighten and damage or break the cable, or cause cable fatigue due to repeated rotation of the motor.

You should use black electrical tape to secure the cable above and below the rotating joint. If you secure the cable with zip ties, do not over-tighten the zip ties.

You should secure the cable above and below the pivot joint of your trolling motor.

You should create a service loop at least 25 cm (10 in.) long in the cable, with the rotating joint centered on the loop.

Routing the Transducer Cable

You should test-fit the transducer and cable before installation.

1. Allow a loose gap of at least 10 cm (4 in.) above and 10 cm (4 in.) ① below the rotating joint ② to create a loop ③ in the cable. The loop must be large enough to allow full rotation of the transducer in both directions. Allow a minimum of 25 cm (10 in.) of cable to cover the 20 cm (8 in.) section between mounting points.
2. Use black electrical tape ④ to secure the transducer cable to the shaft.
3. Test the full rotation of the trolling motor to ensure the cable clears the rotating joint and is not pulled tight due to tension during rotation.

Installing the Transducer on the Perspective Mode Mount

Labels identifying the parts bags required for this procedure: A, B, C

NOTICE

You must secure the transducer cable to the shaft or other secure location during installation. Damage to the transducer cable wire or the cable jacket can cause transducer failure.

NOTE: To avoid obstructions in the sonar image, you should mount the transducer on the shaft as far from the motor as possible.

1. Remove the perspective mode extension arm, the front half of the mounting bracket, and the short knob from parts bag A.
2. Remove the back half of the mounting bracket and four screws from parts bag B.
3. Remove the long knob from parts bag C.
4. If the trolling motor shaft is equal to or less than 25 mm (1 in.) in diameter, remove the rubber liner from parts bag C.
5. Identify the arrow ① on the front half of the mounting bracket to ensure that you orient the bracket with the wide end of the slant ② at the top when you attach the bracket to the trolling motor shaft.

NOTE: The perspective mode bracket has an 11-degree angle to allow the extension arm to transition between all three sonar views.

6. If you are installing the transducer on a trolling motor shaft equal to or less than 25 mm (1 in.) in diameter, wrap the rubber liner ③ around the shaft in the location you want to install the mount.

NOTE: The rubber liner is not needed when installing the transducer on a trolling motor with a shaft diameter larger than 25 mm (1 in.).

7. Orient the mounting bracket ④ on the shaft so the arrows on the inside of the front half of the bracket point up. The bracket should be aligned so the center screw hole faces the front of the trolling motor.
8. Place bracket around the rubber liner on the trolling motor shaft, insert the screws ⑤ into the mount bracket, and secure them using the M5 hex wrench in parts bag C.
9. (Optional) Transition the trolling motor from the deployed to the stowed position and back again to test the location of the mounting bracket and make any adjustments as needed.
10. With the 90-degree angle pointing downward, attach the shorter length of the extension arm to the mounting bracket using the shorter knob ⑥.
11. Place the transducer below the longer length of the extension arm and attach it using the longer knob ⑦.

NOTE: You can secure the extension arm to the mounting bracket and the transducer to the extension arm using the included low-profile hardware instead of the knobs if you do not plan to switch transducer modes frequently during use (Installing the Transducer Using Low Profile Mounting Hardware, page 14).

12. Secure the transducer cable to the motor shaft or other secure location.
13. Route the transducer cable to the installation location of the sonar module while taking these precautions:

• You must route the cable so that it does not come in contact with the propeller when the trolling motor is operating.
• You should not route the cable close to electrical wires or other sources of electrical interference.
• You must route the cable so it is not pinched when the trolling motor is deployed or stowed.

NOTE: If necessary, for extra cable length you can connect an optional extension cable, available at buy.garmin.com or from your Garmin dealer.

14. Position the transducer to your desired angle (Viewing Modes, page 6).

Viewing Modes

Using the perspective mode mount and extension arm, you can change the orientation angle of the transducer between three sonar views.

When installing the transducer using the recommended adjustment knobs, no tools are necessary to change the orientation between these three fields of view. You must loosen the knobs to change the orientation of the arm and transducer, and tighten them to set the orientation.

You can verify the sonar view using the notches on the perspective mount bracket, the shaft mount, and the transducer.

NOTE: The notches are not labeled on the transducer hardware, so you can use these tables and diagrams to understand the positioning of the transducer and perspective view bracket when changing between sonar views.

Viewing Mode Examples on the Port Side

1. Perspective view (notches C and 3)
2. Forward view (notches A and 2)
3. Downward view (notches A and 1)

You should align the marks on the transducer and extension arm to verify the appropriate orientation before tightening the knob.
